The software was a bit intimidating at first, but once you start manipulating it, it's very intuitive. My only issue, and wondering if anyone else has this issue, my LEDS will flash brightly during the transition to day brightness.
Also, on the product description it talks about cloud sweeps, thunderstorms, and moon cycles is there a preset for this? My guess was you'd need to change the time interval and just manually move the leds from bright to low--seems pretty tedious. It would be great to see a preset that you could just layer over certain times or put on random.
And last, once you get used to having wireless control of your equipment with the APEX, it is a little disappointing you can't control the light this way.
Other than the wish list, the light is amazing and the software--once you are used to it--works great. My tank is newly setup and only has fish in it currently so I cant speak to coral reaction/growth.
